For comparison, it loads fine for me right now.
I couldn't load BR or Gap in my web browser for months and it turned out it was a problem with my 'cookies' saved from previous visits. Googling showed me that a lot of people had similar problems.
What web browser do you use? If it is Chrome or Safari, try this to check it: open a "new incognito window" (Chrome) or "new private window" (Safari) and visit the Banana Republic site. Incognito/private windows don't have access to any of your browsing history or cookies, so if that's the problem, the site should load fine.
I don't know how to check in other browsers.
If it is the cookies, you can clear them - but beware that doing so will erase any saved logins, like for instance, you'll have to log into youlookfab again. This is frustrating if you visit a lot of different sites that save your login information.
